I have been into artists doing covers, and I ran across a couple of different artists that are simply amazing, one is guitarist Andrei Cerbu who is Romanian, he is with a group called Iron Cross and he does amazing covers as well as original music, and he has a couple of different female singers he performs with that I think people will love. Another is is Alyona Yarushina, you need to search them out, I think you will be entertained.
